Ep 20. The Hypnotist

The Flintstones season 1 episode 20 titled "The Hypnotist" revolves around the residents of Bedrock getting hypnotized by a traveling hypnotist named "The Great Gazoo." After Fred Flintstone and Barney Rubble make fun of Gazoo's small size and state that they didn't believe in hypnosis, Gazoo takes revenge by hypnotizing them.

As the hypnotized Fred and Barney go about their day, they find themselves behaving in strange ways and making decisions that they later regret. For instance, Fred wants to buy a new car even though he can't afford it, and Barney becomes a daredevil who wants to do things like jumping off the roof of their house.

Meanwhile, Gazoo continues to hypnotize the other residents of Bedrock, including Wilma Flintstone and Betty Rubble. Wilma becomes obsessed with cleaning and becomes a neat freak, while Betty starts acting like a snob and only wants to associate with high-class citizens.

Realizing that something is not right with their friends’ behavior, Fred and Barney set out to get to the bottom of it and eventually confront The Great Gazoo. However, Gazoo reveals that he can only reverse the hypnosis if the two men apologize and admit that they were wrong to make fun of him.

In the end, Fred and Barney apologize and Gazoo restores everyone to their normal selves. The episode ends with Fred and Barney realizing the negative effects of their behavior and Gazoo warning them to never make fun of someone's size or beliefs again.

Overall, "The Hypnotist" is a humorous and adventurous episode that explores the concept of hypnosis and the power of words. It emphasizes the importance of treating others with respect and how our actions can have consequences.
